Kate Middleton’s pregnancy rumors never end.

When Prince Harry and Meghan Markle announced that they are expecting their first bundle of joy, many began looking forward to Prince William and Middleton’s fourth baby announcement. Since then, Middleton’s possible fourth baby has been a hot topic.

In fact, Star magazine claims that the Duke and Duchess of Cambridge are expecting another baby and will be announcing the new addition to their family in the New Year. An alleged source reportedly told the magazine that Prince William and Middleton are happy that they are having another girl.

Express.co.uk reached out to Kensington Palace officials about the matter. According to the publication, the officials declined to comment on Middleton’s pregnancy rumors. However, they said that an official statement would be released if the Duke and Duchess of Cambridge were really expecting.

Prince William and Middleton just welcomed their third baby, Prince Louis, last April. However, many are convinced that the couple is still open to having another child.

In November, Bookies Coral stated that the odds of Prince William and Middleton making a baby announcement went from 2-1 to 1-2. The betting service claimed that there’s a 50 percent chance that the Duke and Duchess of Cambridge could welcome their fourth baby in 2019.

“Our odds show that there’s every chance that Kate and Wills might add to their growing family, and a fourth baby is certainly a possibility,” Coral's Harry Aitkenhead said.

Meanwhile, not everyone agrees that Middleton is eager to have another baby considering the difficulties in her first three pregnancies. The Duchess of Cambridge suffered severe morning sickness that she took a leave following her pregnancy announcement.

"I can’t imagine Kate will want any more given the ordeal that she goes through every pregnancy. I should think that three children are enough," a source told People.

However, according to Ciaran McGrath, a journalist for Express, even the royal mom of three is open to the possibility. Middleton reportedly told her friends that when it comes to the possibility of having more kids, she would "never say never."

Nevertheless, Prince William and Middleton are not in a hurry to welcome another baby.
